This assert lives inside the constructor to the common code generator class RegisterDependencyMap. The assertion fails because numDeps, the second parameter passed into the constructor, is larger (256) than SENTINEL, a constant holding the value 255.

The path we take to get to the fateful execution of this constructor is:

  • OMR::Power::RegisterDependencyConditions::assignPostConditionRegisters
  • OMR::Power::RegisterDependencyGroup::assignRegisters

and the value that ends up becoming numDeps is originally _addCursorForPost, a member variable of RegisterDependencyConditions. It is initialized to zero, and then incremented once in addPostCondition, which makes sense because addPostCondition calls setDependencyInfo to add a register dependency.

Therefore, in order for _addCursorForPost to hold the value 256 by the time it's passed into RegisterDependencyMap, we must call addPostCondition exactly 256 times, meaning we're calling addPostCondition (or adding register dependencies) at least one too many times. There are 143 different places in omr/compiler/p/codegen where we call addPostCondition, and somewhere in that list is likely an edge case where that extra call comes from.

Looking further at the addPostCondition the assert in there which checks with value _numPostConditions for an overflow which is not triggerred, which means that _numPostConditions could be set to value higher than 255.

   {
   TR_ASSERT(_addCursorForPost < _numPostConditions, " Post Condition array bounds overflow");
   _postConditions->setDependencyInfo(_addCursorForPost++, vr, rr, flag);
   }

Added asserts in RegisterDependencyConditions constructors led to assert being taken which trace back to OMR::Power::Machine::createCondForLiveAndSpilledGPRs called from TR_OutOfLineCodeSection::assignRegisters.
https://github.com/eclipse/omr/blob/master/compiler/p/codegen/OMRMachine.cpp#L1826-L1852

In the above code, the spilledRegisterList (231) + RealRegister count turns out to be >= 255, which inturn led to hit the assert in RegisterDependencyMap.

Either SENTINEL set to 255 might be outdated or spilledRegisterList + RealRegister should not exceed 255 which is what is causing this issue and need to be investigated further.

Attached the trace of the method SystemModules$default.moduleHashes:
Though there are only 5 basic blocks, in BBStart <block_2> , there is a large number of stores:

  • that block has lot of commoned registers and lots of spilling happening
  • some of those nodes have really high reference counts, like 147
  • This is causing register dependency to reach limits
  • virtual registers of these nodes will take time to be freed

So, in this case, there are dependencies which can reach max of 255.
To test this, increased the value of SENTINEL=65535. The test passes with this.
